Spearman correlation analysis of RV/TLC and IOS parameters, (A) Z5%pred (r = 0.268∗∗); (B) R5%pred (r = 0.189∗∗); (C) R20%pred (r = −0.060); (D) (R5-R20)%R5∗100 (r = 0.398∗∗); (E) X5 (r = −0.436∗∗); (F) Fres (r = 0.350∗∗); (G) Ax (r = 0.401∗∗). Ax = reactance area, Fres = frequency response, IOS = impulse oscillometry system, %pred = of the predicted value, R20 = resistance at 20 Hz, R5 = resistance at 5 Hz, RV/TLC = residual volume/total lung capacity, X5 = reactance at 5 Hz, Z5 = total respiratory impedance.
